helping granddaughter with math homework

[--Pete]

Hi,

Sometime you may not have your calculator, or cell phone, or whatever it is they use these days to figure 2 + 2.

Never happen. As I sit here, I have a 6" slide rule (don't ask), an HP48GX calculator, a PDA with MathU Pro on it, and a cell phone with a simple four function calculator all within reach. Not to mention the laptop itself, with two calculator apps, MathCad, and -- of course -- XL.:)
